Hi All, Running on Debian, I have a set of users who need to share documents they access by FTP. Only owners of the files can change/delete. I created a common group myshare and set it as primary group to user1 and user2. I have created a common folder /home/share and mounted (mount --bind) the subdirectory I need into the user1 and user2 home dirs I have configured pure-ftp with umasks 137:007 So directories will be writable by anybody in the group and files readable by all. Example: drwxrwx--- 2 user1 myshare 4096 Aug 7 02:55 testdir -rw-r----- 1 user1 myshare 0 Aug 7 02:53 testfile This is great except that files can be deleted or renamed by anybody in the group. I have tried setting the sticky bit for the directories but with no success (I'm not very clear on the sticky bit, is it for others only ?). Any recommendation ? Thanks
Got it working reverting back to different groups for my 2 users. user1: user1 myshare user2: user2 myshare Gave 777 permissions on directories and set sticky bit on upload. directory /home/share is owned by root:myshare and permissions are 770 so people outside the group cannot access it.
